HAIR WAVING EQUIPMENT Filed Nov. 19, 1928 Patented Apr. 29, 1930 UNITEDSTATES WILLIAM G. SHELTON, F ST. LOUIS, MISSOURI HAIR-WAVING EQUIPMENTApplication led November 19, 1928. Serial No. 320,325.

My invention relates to devices for use in effecting a permanent wave orcurl to the human hair and consists in a novel heater curling rod andclamp arrangement.

The objects of my invention are to provide a simple, eective devicewhich may be quickly applied to the hair and ymay be removed easily andwhich, when in position, will securely hold the hair in tightly wrappedconio dition. f

In the accompanying `drawings which .illustrate a selected embodiment ofmy invention- Figure 1 is a perspective of the heater member and theparts mounted thereon.

Figure 2 is a transverse section through the structure shown in Figure 1and also illustrating the curling rod, clamp, pad and4 strand of hair inassembled relation existin 2o during the heating operation.

Figure 3 is a section on the line 3-3 of Figure 2 detailing the curlingrod and one of the` clamp aws but omitting the hair and other featuresshown in Figure 2. Figure A is a detail cross section taken on the line4 4 of Figure 3.

Figure 5 is a top view of the clamp jaws. The operation of lforming acurl or wave is begun by applying the clamp jaws to a strand of hairnear the scalp. Each of the jaws comprises a metallic channel member 1-2having adjacent ends bent towards each other as indicated at 3 andpivotally conv nected by a pin 4. The opposite ends of the 5 and 6. Themajor portions of metal elements 1 and 2 are covered by heavy rubbertubes 7 ywhich form a yieldingsurface for engaging the strand of hairwhichl is gripped by the clamp jaws. By disposing the `channel shapedmetal elements 1 and 2 so that their backs are on the outer side of thedevice, ythe rubber covering is afforded the maximum yielding qualitiesas it may be depressed in between the flanges. p

After the jaws are applied to the strand of hair, the outer end of thestrand is applied to the intermediate portion of the curling rod 8which, at that time, is not attached yto any ofthe other apparatusshown.

ystrand ofhair in the same direction which in one or more of the holes12 and using the jaws mount suitable eccentric clamp elements e .thruststhe lower ends of arms 15 towards Suitable clips 21 are pivoted on eachend of rod 8 and may be folded down over the end of the strand of hairto hold it tightly against the rod and the remainder of the strand ofhair may be readily wrapped over clips 21.

The rod is rotated between the fingers of kthe .operator until thewinding of the hair thereon brings the rod over the clamp'jaws.

vWhen one end of the rod which is equipped -o with the square trunnion 9is adjacent to the upturned flanges 10 provided on the clamp jaws 1,thesquare trunnion 9 will lit in the groove G. The trunnion 9 has acylindrical inner vportion journalled in the curling rod and this innerportion i's provided with an annular groove in which is mounted a springwire 11 adapted to contact with the inner face of the trunnion receivingopening in the curling rod. This wire, being shaped as shown, willpermit the curling rod to rotate on the trunnion in one direction, butwill resist rotation in the opposite direction.

The curling rod may be wound upon the will permit relative rotation vofthe curling rod and trunnion. Then, after the trunnion is seated in thegroove G, the curling rod lnay be slightly rotated by inserting a pinpin `as a crank. This will tighten the strand of hair on the curling rodand also. by means of shortening the unwrapped portion of the strand ofhair, hold the curling rodV tightly. against the jaws of the clamp.

The heater member is then slipped over the curlin rod and the strand ofhair wrapped t ereon and this` heater member comprises an arcuate bodyportion 13 having an electric resistance heating element embeddedtherein. A block 14 of insulation is attached to the top ofthe heatermember 13 and a pair of arms 15 are pivotally mounted.

at 1,6 upon block A14. A suitable spring 17 tube 19. loo

These bars 18 with their covering are applied to the joints between thecurling rod and the clamp jaws as shown in Figure 2 and serve toyieldingly hold the heater in position and also serve to insulate theheater member from the clamp jaws and thereby protect the rubbercovering 7 of the metal portions 1 and 2 of the clamp jaws.

Preferably, a pad of gauze, felt or blotting paper is saturated with asetting liquid and applied to the strand of hair as it is wrapped uponthe curling rod. Such a pad is shown at 20 and it will be understoodthat pads of this type are old in theart and, in themselves, form nopart of my present invention. When such a pad is used, the bars 18 serveto hold the pad in place and also serve to absorb hot water and steamgenerated by the heating operation which tends to seep down between thecurling rod and the clamp jaws and contact with the scalp of the user.

The device described is very simple and is easily applied and removedand avoids the use of more cumbersome and complicated clamps andassociated devices previously7 used in equipment of this type.

It is obvious that any detail of the described structure may besubstantially modified and I contemplate the exclusive use of anyvariations in details which come within the scope of my claims.

I claim:

1. In a clamp for a hair waving device, a pair of clamping jaws eachcomprising a channel-shaped metal element and a rubber coveringrstretched over said element, the channel of one of said jaws facing thechannel of the other of said jaws whereby the portions of the rubbercovering stretched across said channels are opposed to each other' andmay vield inwardly of their respective aws.

2. In a device of the class described` a hair clamping structure havingan upstanding flange provided with an upwardly opening groove, a curlingrod having a trunnion rotatably mounted in one end thereof and having anon-circular projection adapted to tit in said groove, and frictionmeans between said rod and trunnion and inside of said a'od forpreventing relative rotation of said trunnion and rod in one direction.

3. In a device of the class described, a heater member, an arm pivotedon said heater` means for thrusting the lower end of said arm in onedirection and moving it relative to the adjacent portion of said member,and an element on said arm beneath said heater member for engaging astrand of hair.-

4. In a device of the class described, a heater member` arms pivoted onsaid heater member and projecting below the same, means for thrustingthe vlower ends of said arms towards each other and moving them relativeto the adjacent portions of said member, and elements on said armsbeneath said heater member for gripping a strand of hair between them.

5. In a device of the class described, an elongated concaved heatermember, arms pivoted on said member and projecting'below the edges ofthe same, and individual bars on the lower ends of each of said arms andextending along the adjacent lower edges of said heater member andmovable relative to said edges and adapted to grip a strand 7. In adevice of the class described, an

elongated semi-cylindrical heater member, a relatively short block onthe convex side of said member, arms pivotally mounted on said block andextending on opposite side of said heater member to below thelongitudinal edges of the same, bars mounted on the lower ends of saidarms and extending adjacent to said member edges, and a spring appliedto said arms so as to thrust the lower ends of the same and said barstowards reach other beneath said heater member edges.

8. In a clamp for a hair waving device, a pair of clamping jaws, eachcomprising spaced rigid metal elements and a rubber covering stretchedthereover, said jaws being arranged so that spaces between theirrespective elements are opposed whereby the portions of the rubbercovering stretched across the said elements are opposed to each otherand may yield inwardly of their respective jaws.

In testimony whereof I hereunto affix my signature this 13th day ofNovemberf1928.

IVILLIAM G. SHELTON.
